For some reason I remember as a kid going to the park and being surprized that it was there.
I also remember it not being there when i went to Fright Fest as a kid. The circular cement pad was there, but behind the chain-link fence there was the Batmobile and actors dressed up as rats. (they were eating popcorn people were "feeding" them. weird, right?

Was I dreaming? or was Whirlygig removed at one point?
